I’m trying to use acf_add_validation_error, but it doesn’t show the error for the input. Does anyone know how to make this work properly?

Here is my example:

acf_add_validation_error( 'first_name', 'Required' );

acf_add_validation_error() is not a documented ACF function.

This is the ACF documentation for adding validation to fields https://www.advancedcustomfields.com/resources/acf-validate_value/

For future reference, this function is referred to here: https://www.advancedcustomfields.com/resources/acf-validate_save_post/

It will work if you use the selector within the input name. Should be something such as acf[field_5b1e124565677].

acf_add_validation_error( 'acf[field_5b1e124565677]', 'Required' );

Thanks @sloconte, after all this time I can still learn something new.
